Quad core worth it?

Hi therePosted a few times before about upgrading my system, so sorry if this is getting tedious.

I currently run an Intel Core2 Duo e6600 2.4ghz CPU, and i will upgrade but deciding what to.Since i will only play D3 as the most demanding game i feel no need to spend big bucks on a top gaming system. I'm getting a 6850 as an upgrade from a 4850 and will upgrade my CPU aswell. I only have a 775 socket mobo atm which makes getting a new i5 or i7 impossible without upgrading my motherboard, but i'm wondering if it is worth getting a Core 2 Quad or just stick with a higher ghz Core 2 Duo - such as a 3.0ghz?

Sorry to waffle, i guess the crux of the question is whether D3 needs a quad core to run well - or would a 3.0ghz dual core suffice?

Dual cores are starting to show their age now, and it seems that diablo 3 is a cpu intensive game atm.

For example, when I play beta, its using around 35% of my GPU, the rest is CPU, I have an i5 2500k @ 4.2ghz so it handles it well, but on a dual core you might struggle, unless ofc you turn down the graphics settings, but its so much better with the eye candy on high.

Hopefully blizz will optimise the engine before release so it uses more gpu power and relies less on cpu.

You can max out graphics settings but only thing you need to lower are the physix (sorry for miss spelling... ) that effect yours cpu but if you want all maxed out ye quad core is the way to go ... i might upgrade my dual core as well to quad.

have dual core 3.2ghz and 560ti amp! gtx card... 1920-1080 resolution no problems only problems are the one mention up .

Your calculations are wrong.

Zoofie first try to play D3 and then go for a upgrade if needed. I think your cpu will be enough for high.

Very good advice, cheers mate!I will at least get it playable with 2.4ghz and HD 6850, whether it be medium or low. Then after i can decide if it needs upgrading. I will only be playing at 1400x900 also!Thanks, i've never been so wound up about a game getting released before lol - just can't wait to play it! :P
